texture format question

im pretty sure i already know the answer to this, but if im wrong, it may help me out a lot. i always load .bmp files to create textures, but would loading .jpg files reduce the size of textures in video memory? i dont think they would cause it seems to me that all texture data would be in a single format, no matter how its loaded. eh?

No, it wouldn''t change the size in memory, only on disk. When a .JPG is loaded, it is uncompressed into a full bitmap of the specified dimensions.

The only way to decrease the size in memory(outside of scaling the image) is to use texture compression extensions.
